问题 下列哪种疾病可引起外周血网织红细胞绝对值减少( )
选项 A、缺铁性贫血 B、巨幼细胞性贫血 C、溶血性贫血 D、再生障碍性贫血 E、慢性失血性贫血
答案 D
解析 缺铁性贫血、巨幼细胞性贫血、溶血性贫血等属于增生性贫血,骨髓代偿性增生,网织红细胞是反应骨髓红系增生的指标,故除再生障碍性贫血网织红细胞减少外,其余几种贫血网织红细胞多增高。

错误啦!

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
